In a word "Jawsome."
Heck, ask yourself why English adds an S to the end of plurals when German doesn't.
That's not so clear cut, and I hope you don't mind my irrelevant aside. It's something of an anquitated view now to regard the
-s plural ending as derving from Latin or Anglo-Norman French, as similar
-as,
-os, and
-oz plural endings could also be found in Old English, Proto-West Germanic, and Proto-Germanic, respectively. I believe that the nominative plural reconstructed for PIE is also
-oes. I recall reading that the -
as plural was used for A-stem nouns in Old English, but this shifted to
-es and simply to
-s over time and became the general plural ending for nouns. Someone with actual linguistic training in Old English or Germanic languages could tell you better.
Old English: wulf -> wulfas
Old Saxon: wulf -> wulfas
High German (commonly just "German") isn't really some sort of Ur-form for English or even West Germanic languages. Modern day High German represents the German dialect/language that won out (and subsequently imposed) as the dialect chosen for unifying the German nation-state. It's similar to how Tuscan was selected by the Kingdom of Italy to be the derivation for the standarized Italian language. It's something of an artificial product of modern 19th century nationalism.
For a long time most of northern Germany spoke the Plattdeutsch / Low German language,* which derives from Old Saxon, making it closer kin to Old English than High German. Plattdeutsch served as the lingua franca for trade in the North Sea and Baltic during the Middle Ages as a result of the Hansa League. (Plattdeutsch subsequently had a
strong influence on Scandinavian languages and vocabulary.) There are a number of consonant sound shifts that affected High German that did not affect Plattdeutsch, which makes the latter somewhat easier IMHO to understand than the former. And low and behold, one can find -s plural endings in Plattdeutsch, though one can also find
-(e)r and
-(e)n plurals that are closer to the neighboring High German. Plattdeutsch has different dialects, much like High German has. I believe that Dutch also has multiple noun plural endings, including
-s as well.
* My partner comes from a town in North-Rhine Westphalia. They speak High German natively, but several of their grandparents were native Plattdeutsch speakers and a number of the signs in the town are still in Plattdeutsch.
